Abstract
Stress development during co-firing a multilayer dielectric material of Bi 2 (Zn 1/3 Nb 2/3 ) 2 O 7 (BZN) and magnetic material of (Ni 0.3 Cu 0.1 Zn 0.6 O)- (Fe 2 O 3 ) 0.8 (NiCuZn ferrite) laminate has been investigated by measuring camber development and shrinkage rate difference. The trend of camber development follows a similar pattern to the linear shrinkage rate difference between NiCuZn ferrite and BZN. No co-firing defects are observed in the multilayer structure of NiCuZn ferrite and BZN laminates, which is attributed to good sintering compatibility between these two ceramics, and the sintering mismatch stress generated in the laminate much less than those of sintering potentials. © 2011 The American Ceramic Society.
